2. Of Apollonia, a disciple of Isocrates of Athens (No. 1), with whom he has often been confounded. He appears, however, to have enjoyed a considerable reputation as an orator, for he is mentioned among those who competed with other orators for the prize which Artemisia of Caria proposed in the literary contest which she instituted in honour of her husband Mausolus, in B. C. 352. Suidas mentions the titles of five of his orations, but none of them have come down to us. (Epist. Socrat. xxviii. pp. 65, 67; Suid. s. v. Ἰσοκράτης; Eudoc. p. 247; Spalding, ad Quintil. 2.15.4.) Some critics believe that he was the author of the τέχνη ῥητορικὴ, which was mentioned above among the works of his master and namesake. (Westermann, Gesch. d. Griech. Beredtsamk. § 50, notes 3 and 4.68, note 15.)
